Key changes v0.3 => v0.4:
- made idle workers list logic simpler
- only one idle server tracking
- removed two fields from struct umcg_task
- added timeout handling
- added worker preemption

  transitions.

More details on the state of the patchset and future work are provided
in the patch 4 commit message.
